An electrode extension guide for use with welding systems is provided. This electrode extension guide includes a barrel adapted to be connected to a contact tip, wherein the barrel has a predetermined length, a predetermined outer diameter, a predetermined inner diameter, and a plurality of apertures formed therein, wherein each aperture extends from the outer diameter through to the inner diameter of the barrel, and wherein the inner diameter further defines a channel passing lengthwise through the barrel; a plurality of bearings, wherein each bearing is inserted into one of the apertures formed in the barrel such that the bearing extends a predetermined distance into the channel, and wherein each bearing is electrically non- conductive; and a sleeve disposed around the outer diameter of the barrel along the length thereof, wherein the sleeve is operative to retain the bearings within the apertures at the outer diameter of the barrel. |
